Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042148, here are decompositions:

7 + 1042141 = 1042148
61 + 1042087 = 1042148
67 + 1042081 = 1042148
109 + 1042039 = 1042148
127 + 1042021 = 1042148
157 + 1041991 = 1042148
199 + 1041949 = 1042148
229 + 1041919 = 1042148

Showing the first eight; more decompositions exist.
